This invention relates to new and useful improvements in latches forWindows or the like. The invention has for an object the pro vision of adevice of the class mentioned which is of simple durable construction,dependable in use and eflicient in action, and Which can be manufacturedand sold at a reasonable cost. t

The invention proposes the use of two separate latch sections, one forattachment upon one of the two members tobe latched together, and theother for attachment on the second member, the first latch section tohave a latch arm hingedly mounted and extendible across the second latchsection, and the second latch section to have a latch arm pivotallymounted and movable across the said latch arm for holding the latch armof the first section in locked position.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in whichthevarious novel features of the invention are more particularly setforth.

In the-accompanying. drawing forming a material part of this disclosure5- Fig. 1 is a front elevational view of two members to belatchedtogether, and provided with a latch constructed according to thisinvention.

A latch section 12"is attached upon the" stat.

tionary frame l Qand a second latch section 13 upon the movable window11.. The latch SGCtlOIl 1 2 has a latch arm 14 hingedly mounted andextendible acrossthe latch section 12 while the latchsection 13 has apivotally mounted latch arm 15 movable across the latch arm 14: forholding the latch arm 2 1 1 1n a locked position.

The latch section 12 consists of a block 16 formed with a transversegroove 17 and a so strip 18 is fixed on the base of the groove and hasan upturned rear end 19. The latch arm 14; is hingedly connected to thefront end of the strip 18 as at 20 and a spring 21 1S coax ally mountedon the hinge20 and acts between. the strip,18' and the latch arm 14; fornormally urging the latch arm upwards against the upturned end 19 asseen in Fig. 4. i

I The second latch section 13 consists of a block 22 secured upon themovable window member 11 and formed with a longitudinal lange 23 alongone of its sides. This flange projects abovetlie top surface of theblock and the central portion of the flange is bent at right angles tothe main portion as indi- 1 cated by reference numeral 23. This providesa passage so that the latch arm 14 may pass between the sections of-theflange and rest fiat against the block 22. The latch arm so 15 ispivotally mounted on the top of the bloclr'22 asiat 24 and is arrangedto swing across the top of the latch arm 14 when the latter arm is initslowered position. The portion 23 of theflangehasa cutoutindicated s5bynumeral25 in Fig. 3 so that the latch arm 15 may engage underneath.The free end of the latch arm is'turned upwardsto'form a handle portion26. V A spring 27; iscoanially mounted on the pivot. point of the latcharm to 1 and betw en. th block 22 endthe l m rm f ers 1:3. urgingthe lach; m a ns the flan e 2 ea Sha n. in; Ha Dlqt and dash lines 2 8- in iate nother p 'si dl f t e la ch a m. 15 town '11 it y be m lly m ed forper it s the spi i g raie 'the a h: l t9 ite f'a j l P5$ Qn-- It s. p tularly pelt-t net? that-the l c arm: lemeresi in a; p.. tr jh a gles ton the longitudinal. length" (if the tied; it: The we latch arm 15 movesin a plane parallel to the longitudinal length of the block 22. For thisreason when the latch arm 15 is engaged across the top of the latch arm14 it securely holds the same in a locked position. Persons attemptingto jimmy the window may insert a knife or other implement between thestationary frame and the movable window but cannot move the latch arm 14for causing an unlocking thereof.

In Figs. 5 and 6 the same latchhas been shown applied to an inner andouter window sash for latching a window in a closed position. Thereference numeral 29 indicates the outer window sash which has ahorizontal bottom member 30 upon which the latch section 12 is attached.The inner window sash is'indicated by numeral 31 and this sash has ahorizontal top member .32 upon which the second latch section 13 issecured. Since the latch arm 14 of the latch section 12 extends acrossthe second latch section 13 and is held in latched position by thepivoted. arm 15 ot this section the windowsashes are locked. In Fig. 6numerals 33 indicate the jamb members of a window frame in which thesashes operate.

In operation of the device the latch arm 14: is manually moved down intoits latching position and the latching arm 15 pivoted across the top ofthe latch arm 14 forholding it in lock-ed position. In this condition ofthe device the two members are latched together and cannot be moved. ForOpening the latch it is merely necessary to manually move the latch arm15 against the action of the spring 27. As soon as the arm 15 is movedtree from the arm '14 the spring 21 will automat cally raise the arm 14to its inoperative position. When the arm 15 is released, the spring 27will urge the same against the flange and the device will remain in thiscondition, in which the two members may be moved without interference.
